Allen Bradley Devicenet Error Codes

Contents

The system returned: (22) Invalid argument The remote host or network may be down. I will throw a recorder on that today to see if it is a possibility. When we do this the problem clears and all is well for another few hours. It's easy! his comment is here

The problem is very intermittent and occurs 3 or 4 times each day. I have checked all the nodes and adapters for solid connection and all seems well. Perhaps somebody has locked-out a DN remote rack somewhere, or locked-out a Drive. I really appreciate all the responses and we can pick it up next week. http://www.plctalk.net/qanda/showthread.php?t=45205

What is the device? Error # 78 indicates that the scanner module is trying to establish or re-establish communications with a slave device. As far as it being a single node or system wide the panel view is communicating via devicenet and it seems to be fine. Devicenet Error 77 If several devices are turned off, then a succession of "78"'s followed by each of these node numbers will display.

Anyway, a Bus-Off condition can be cleared by cycling power on the slave. 1769-sdn Error Codes Your cache administrator is webmaster.

Are the codes the same for Control logix devicenet modules? This error code says the scanner lost the scan list...is this a common problem?

Probably, you have a Motor Control Center containing Variable Frequency Drives, each of which is connected as a DeviceNet Node. http://missioncritiallinux.com/error-code/allen-bradley-error-code-0187h.html The problem is that you can't get anywhere near the Flex I/O adapters until the equipment is stopped and by that time everything is cool except the processor and the DNB Please try the request again.

The issue is probably that this is rotating equipment and sends the comms over slip rings (wich seem ok) .

Been there....done that. I vaguely remember that Slave may go into a "bus off" condition which, though green, will be indicated by the comm LED flashing green (though I'm less sure about this one Odds are you have a loose or bad connection to the node or nodes that are dropping off of the network. Rsnetworx For Devicenet I swapped the most signifigant and the least signifigant digit.

The other thing that is strange is that it only occurs after 2:30 in the afternoon so I was thinking it might be related to the incoming Edison service dropping voltage Typically it will flash the error code "78" followed by the node number "0-63" that has dropped of the network. What do the indicators on the device say? check over here On the 1756-DNB they are accompanied by "N#" for node number and "E#" for error number.
